Description

Die Erfindung betrifft einen Anlaufring eines Planetwalzenextruders, der zur Verbindung von Planetwalzenteilen geeignet ist.The Invention relates to a thrust ring of a planetary roller extruder, which is suitable for connecting planetary roller parts.

Eine Massetemperaturmessung ist bei bekannten Extrusionsmaschinen weit verbreitet und wird am Ende der eigentlichen Extrusionseinrichtung durchgeführt, indem das Meßmittel in einem anschließenden Flansch eingebaut wird und dort in die Masse eintaucht. Nach diesem Prinzip sind auch verschiedene Ausführungen von nachgeschalteten Massetemperaturmessungen für das System Planetwalzenextruder bekannt.A Mass temperature measurement is far in known extrusion machines disseminated and performed at the end of the actual extrusion device by the measuring means in a subsequent Flange is installed and immersed in the mass. After this The principle is also different versions of downstream mass temperature measurements for the System planetary roller extruder known.

Diese Vorgehensweise ist nach heutigem Stand erforderlich, da in kontinuierlich arbeitenden Extrusionsmaschinen die Ermittlung der Massetemperatur schwierig ist, da die meisten Extrusionsmaschinen mit Schnecken oder Kolben einen Zylinderinnenraum mehr oder weniger häufig abstreifen und somit ein Meßmittel, welches in die Masse hineinreicht, unmittelbar beschädigen oder zerstören würden.These Procedure is required to date, as in continuous working extrusion machines to determine the melt temperature difficult, since most extrusion machines with screws or piston strip a cylinder interior more or less frequently and thus a measuring means, which extends into the mass, directly damaging or to destroy would.

Die bekannten Planetwalzenextruder sind mitunter aus hintereinandergeschalteten Planetwalzenteilen oder Planetwalzensegmenten zusammengesetzt. Zwischen diesen Segmenten sind häufig sogenannte Anlaufringe (auch als Dispergierringe, Stauringe oder Kombinationsringe bekannt) eingesetzt.The known planetary roller extruders are sometimes made of successive Planetwalzenteile or Planetwalzensegmenten zusammengesetzt. Between These segments are common so-called contact rings (also as dispersing rings, retention rings or Combination rings known) used.

Bekannterweise sollte zur Prozeßsteuerung und -regelung die Massetemperatur möglichst im Prozeßraum gemessen und somit zur Prozeßsteuerung genutzt werden können. Die bekannte nachgeschaltete Massetemperaturmessung bedingt eine Totzeit zwischen dem Entstehen der Temperatur (z.B. durch Friktion oder Wärmeübertragung) und läßt so nur wenig Rückschluß über den Verlauf der Massetemperatur zu. Zudem erfaßt man nur die gemittelte Temperatur, besonders wenn im Extruder, wie in der Extrusion üblich, am Ende der Extrusionsmaschine die Mischarbeit erfolgt und verschiedene Massetemperaturströmungen zu einer mittleren Temperatur vereinheitlicht werden. Die Messung erfolgt demnach über einen langen Abschnitt in nur unzureichender Weise. Besonders wenn ein Planetwalzenextruder über den Extrusionsprozeß hinaus als Reaktor genutzt werden soll, wäre für die Reaktionssteuerung eine Massetemperaturmessung während des Prozesses ein deutlicher Fortschritt zur Prozeßführung.known manner should be used for process control and Control the melt temperature as possible in the process room measured and thus for process control can be used. The known downstream mass temperature measurement causes a dead time between the formation of the temperature (e.g., by friction or Heat transfer) and so lets only little inference about the Course of the melt temperature. In addition, only the average temperature is recorded, especially when in the extruder, as usual in extrusion, on End of the extrusion machine, the mixing work is done and different mass temperature flows unified at a medium temperature. The measurement takes place via a long section in an inadequate way. Especially when a planetary roller extruder over the extrusion process would be used as a reactor, would be for the reaction control a Mass temperature measurement during the Process a significant step forward for litigation.

Aufgabe der Erfindung ist es, in einem Planetwalzenextruder das Messen der Massetemperatur in einem Extruderabschnitt zu ermöglichen. Weiterhin soll eine Messung an mehren Stellen des Umfanges sowie entlang der Walzenteilachse ermöglicht werden.task The invention is in a planetary roller extruder measuring the Allow melt temperature in an extruder section. Furthermore, a measurement at several points of the circumference as well be made possible along the roller part axis.

Die Lösung der Aufgabe ist in Verbindung mit dem Oberbegriff des Anspruches 1 dadurch gekennzeichnet, dass der Anlaufring mit mindestens einer Bohrung versehen ist, die zur Aufnahme eines Meßmittels geeignet ist. Dies hat den Vorteil, daß ein in geeigneter Weise konstruierter Anlaufring eine Meßmittelaufnahme bietet, bei der das Meßmittel in keinster Weise in einen Bereich der Extrusionsmaschine hineinragt, in der drehende Teile an der Zylinderinnenwand vorbeistreifen, aber ungehindert die Masseeigenschaften wie Temperatur ermitteln kann. Die Bohrung ist vorteilhafterweise mit einem Gewinde versehen, damit das Meßmittel eingeschraubt werden kann. Besonders vorteilhaft ist es, wenn das Gewinde ein sogenanntes bekanntes und übliches UNF-Gewinde ist. Das Meßmittel selbst kann unterschiedliche Längen aufweisen, die beispielsweise 5, 10 oder 20 mm oder ähnliche Längen betragen. Somit ist eine Messung in verschiedenen Eintauchtiefen möglich. Das Gewinde sollte vorzugsweise ein ½''-Gewinde sein, damit handelsübliche Meßmittel eingesetzt werden können.The solution the object is in connection with the preamble of the claim 1, characterized in that the stop ring with at least one bore is provided, which is suitable for receiving a measuring means. This has the advantage that a suitably constructed stop ring a Meßmittelaufnahme offers, where the measuring means in no way protrudes into an area of the extrusion machine, but pass in the rotating parts on the cylinder inner wall unhindered to determine the mass properties such as temperature. The bore is advantageously threaded so that the measuring means can be screwed. It is particularly advantageous if the Thread is a so-called known and usual UNF thread. The measuring means itself can have different lengths have, for example, 5, 10 or 20 mm or similar lengths be. Thus, a measurement in different immersion depths is possible. The Thread should preferably be a ½ '' thread be so commercial Measuring device used can be.

In einer Weiterbildung ist der Anlaufring mit mehreren Bohrungen radial am Umfang des Anlaufringes ausgeführt. Es ist hierdurch möglich, auch die Meßmittel an verschiedenen Positionen radial am Umfang des Ringes einzubringen.In a further development is the thrust ring with a plurality of bores radially executed on the circumference of the stop ring. It is possible by doing so, too the measuring means to introduce radially at different positions on the circumference of the ring.

Als Meßmittel wird vorgeschlagen, einen Massetemperaturaufnehmer einzusetzen.When measuring means It is proposed to use a mass temperature sensor.

In die Öffnungen bzw. Bohrungen des Anlaufringes kann selbstverständlich als Meßmittel auch ein Druckaufnehmer eingebracht werden. Es ist auch möglich, einen sogenannten Kombinationsaufnehmer einzusetzen, der sowohl Massedruck als auch Massetemperatur ermitteln kann.In the openings or holes of the stop ring can of course as a measuring means also a pressure transducer can be introduced. It is also possible to have one use so-called combination sensor, which is both mass pressure as well as melt temperature can determine.

Dieser erfindungsgemäß vorgeschlagene Anlaufring eignet sich besonders zum Einsatz in Planetwalzenextrudern, wobei dieser aus mehreren Planetwalzenteilen zusammengesetzt ist und der Anlaufring diese Planetwalzenteile verbindet. Es ist somit möglich, die Messung an verschiedenen Stellen im Prozeß durchzuführen, so daß die Temperatur auch zur Prozeßsteuerung und Prozeßautomatisierung genutzt werden kann.This According to the invention proposed stop ring is particularly suitable for use in planetary roller extruders, wherein this is composed of several planetary gear parts and the Thrust ring connects these planetary roller parts. It is thus possible the Perform measurement at various points in the process, so that the temperature for process control and process automation can be used.

In der Zeichnung ist ein Ausführungsbeispiel eines Anlaufringes 1 dargestellt, wobei der Anlaufring 1 eine Bohrung 2 aufweist, die mit einem Gewinde 3 versehen ist, in die ein Meßmittel 4 eingeschraubt wurde. Das Meßmittel 4 hat einen Meßfühler, der in das Innere des Anlaufringes hineinragt. Eine Schnittdarstellung gemäß Schnitt AA zeigt die 2, die wiederum den Anlaufring 1 mit der Bohrung 2 und dem Gewinde 3 zeigt. Ein innerer Abschnitt des Meßmittels 4 ist kurz oben dargestellt.In the drawing, an embodiment of a stop ring 1 shown, wherein the stop ring 1 a hole 2 that has a thread 3 is provided, in which a measuring means 4 was screwed.
